Hi Jens,
I ran with your suggestion and DM now sees a ~7% improvement in hipri
bio polling with io_uring (using dm-linear on null_blk, IOPS went from
900K to 966K).
I'd appreciate it if you could pick up the first patch for 5.19.
I'll rebase dm's 5.19 branch on block once it lands.
(FYI, this series builds on linux-dm.git's "dm-5.18" branch, and the
commits in this series are available in linux-dm.git's "dm-5.19"
branch).
Thanks,
Mike

dm: conditionally enable BIOSET_PERCPU_CACHE for bio-based dm_io bioset
